Pendulum CNT-90 Series Programmer's Handbook

Command Reference 8-53
+
The array size for :MEASure and :CONFigure, and the channels, are expression
data that must be within parentheses ( ).
The question mark at the end of the commands is only valid for :MEASure,
where a result is expected. It must be deleted for :CONFigure, which is a set
-
ting command only.
The default channels, which the counter use when you omit the channels in the
command, are printed in italics in the channel list on the following pages.
+
If you want to check what function and channels the counter is currently using,
send :CONF?
This query gives the same answer as :FUNC? in the SENSe subsystem
